Next, on the basis of the recording history information D22, the viewing history information D23, the EPG data D2, the ECG data D3, and the series information D15, one or more broadcast programs belonging to the series to be recorded by the user are selected. An operation of detecting the viewing / recording situation will be described.

7 is a flowchart illustrating an operation of detecting viewing / recording conditions of one or more broadcast programs belonging to a series of recording targets of a user.

The series broadcast program viewing / recording situation detection unit 23 starts from the user via the input operation unit 405 or the remote controller 5, and the inquiry request R8 of the series broadcast program viewing / recording situation is input. The series information D15 is obtained from the EPG / ECG / series information storing unit 15 (step S301).

Next, the series broadcast program viewing / recording situation detection unit 23 stores all the broadcast programs belonging to the same series from the EPG data D2 and the ECG data D3 stored in the EPG / ECG / series information storage unit 15. (Step S302). Since the series information D15 includes broadcast program IDs of all broadcast programs belonging to the series, the search for broadcast programs belonging to the series is performed from the EPG data D2 and the ECG data D3 using the broadcast program ID as a key. It is possible to do.

As a result of this search, if the corresponding program is not found in the EPG data D2 and the ECG data D3 (NO in step S303), the series broadcast program viewing / recording situation detection unit 23 does nothing and ends the process. do. In addition, when a corresponding program is found in the EPG data D2 and the ECG data D3 (YES in step S303), the series broadcast program viewing / recording situation detection unit 23 performs the EPG data D2 and the ECG data D3. For each broadcast program found in the above), the viewing history information D23 of the corresponding broadcast program is retrieved from the viewing history storage unit 20 using the broadcast program ID as a key, and the corresponding recording program is stored from the recording history storage unit 22. The recording history information (D22) of the broadcast program is retrieved. The series broadcast program viewing / recording situation detection unit 23 is based on the viewing history information D23 and the recording history information D22 of the corresponding broadcast program, and for each broadcast program belonging to the series, this may be viewed. It is determined whether the program is a broadcast program or a broadcast program that is reserved for recording. Thereby, the information of the viewing / recording status of one or more broadcast programs belonging to the series to be viewed by the user can be obtained (step S304). Here, the series to be viewed by the user means that the series is a series of broadcast programs that are supposed to be viewed or recorded by the user.

Thereafter, the series broadcast program viewing / recording situation detection unit 23 organizes and edits the information of the viewing / recording situation for each of one or more broadcast programs belonging to the series to be watched by the user, and generates data D20 on the output screen. (Step S305), the data D20 of this output screen is output to the external AV device 4 via the AV interface 406 (step S306). As a result, the external AV device 4 displays an output screen of the viewing / recording status of one or more broadcast programs belonging to the user's viewing target series.

8 is a diagram illustrating a first example of an output screen of a series broadcast program viewing / recording situation.

The series broadcast program viewing / recording situation detection unit 23 is based on the recording history information D22, the viewing history information D23, the EPG data D2, the ECG data D3, and the series information D15. A plurality of broadcast programs belonging to the target series are classified into broadcast programs that have not been viewed or recorded, broadcast programs that have been recorded but not watched, and broadcast programs that have been recorded and watched. The series broadcast program viewing / recording situation detection unit 23 organizes the information on the broadcast program for each classification and generates the data D20 of the output screen.

In the example of the output screen of FIG. 8, as a series to be viewed by the user, a series whose series name is "drama, broadcast program α" is detected, and among the broadcast programs belonging to this series, no broadcast or video recording is performed. The broadcast program name indicates that three broadcast programs α, 10 episodes, broadcast program α, first episode, and broadcast program α, second episode have been found. At least, the broadcast program that is scheduled to be distributed in the future is a broadcast program that has not been viewed or recorded in this way, and is detected by the series broadcast program viewing / recording status detection unit 23, and outputs the output screen of the external AV device 4. Is presented to the user. Alternatively, programs that are currently available for distribution, which are neither watched nor recorded, are presented to the user at the same time. As a result, the user can easily identify a broadcast program that is scheduled to be distributed in the future in a broadcast program belonging to a series that the user wishes to record or watch, or a broadcast program that is currently being distributed but has not yet been recorded or watched.

On the output screen of the series broadcast program viewing / recording situation, information indicating the delivery method of the broadcast program corresponding to, for example, "broadcasting" "VOD" is displayed in correspondence with the broadcasting program that neither recording nor watching is performed. As a result, the user can grasp at a glance how to distribute a broadcast program that is neither recorded nor watched, and is useful information when the recording program is scheduled for recording.

In the example of the output screen of the series broadcast program viewing / recording situation shown in Fig. 8, the broadcast program names of the broadcast programs recorded but not watched are five broadcast program names of " Broadcast program α, the third to seventh episodes " As the broadcast program names of broadcast programs that have been recorded and viewed, two broadcast program names " broadcast program α, episode 8 and episode 9 " are displayed. Thereby, the user can grasp | ascertain the completed program and the broadcast program which he / she did not watch among the recorded programs at a glance.

In the example of the output screen of the series broadcast program viewing / recording situation of FIG. 8, only the broadcast program name and the delivery method of the broadcast program that have neither been recorded nor watched are displayed. Other information obtained from EPG / ECG, such as delivery date and time, may be displayed together. When there are a plurality of series to be viewed by the user, the output screen of FIG. 8 is generated for each series and displayed.

9 is a diagram illustrating a second example of an output screen of a series broadcast program viewing / recording situation.

This example does not classify the broadcast programs according to the viewing / recording status. Instead, the viewing / recording statuses of one or more broadcast programs belonging to the series to be watched by the user are arranged one by one according to the sequence number of the broadcasting program. It is displayed. The viewing and recording of individual broadcast programs is made available to the user by display information such as text information such as "VOD", "broadcasting", "recording completed", and "viewing completed" or pictogram information. Here, the display information of "VOD" is a broadcast program that neither viewing nor recording has been performed, and indicates that the broadcast program is scheduled for VOD distribution or a broadcast program that is currently capable of VOD distribution. The display information of "broadcast" indicates that the broadcast program has neither been viewed nor recorded, and that the broadcast program is scheduled for broadcast distribution. The display information of " recording completed " indicates that the program is recorded but not watched. The display information of "view completion" indicates that the program has already been viewed. In this way, the viewing and recording statuses of one or more broadcast programs belonging to the series to be viewed by the user are displayed one by one according to the conference sequence of the broadcast program, thereby viewing and recording one or more broadcast programs belonging to the series to be viewed by the user. The situation can be grasped by the user at a glance.

As described above, according to the present embodiment, the user's viewing target is based on the recording history information D22, the viewing history information D23, the EPG data D2, the ECG data D3, and the series information D15. By detecting the viewing / recording status of one or more broadcast programs belonging to the series, it is possible to satisfactorily record the series broadcast program without being influenced by the change of the broadcast date or the delivery date of the broadcast program.

In addition, according to the present embodiment, the viewing / recording status of one or more broadcast programs belonging to the series to be viewed can be detected over a plurality of different delivery methods. Thus, for example, even if a user who wants to continuously record a series of broadcast programs distributed by a predetermined delivery method has failed to record any conference broadcast program, the conference broadcast program will be distributed by another delivery method. If so, it can be notified to the user. Here, for example, terrestrial analog broadcast, terrestrial digital broadcast, BS broadcast, CS broadcast, IP multicast method, VOD method and the like are exemplified in the delivery method, but the present invention is not limited to the type of the delivery method. Moreover, it is not restrict | limited also to the selection method of another several delivery system.

The functional configuration mounted in the recording apparatus 400 of the present embodiment can also be configured as a program such as an application program for operating a computer. This program can be distributed by storing in a computer-readable storage medium.

In addition, this invention is not limited only to embodiment mentioned above, Of course, various updates can be added within the range which does not deviate from the summary of this invention.
